Abstract: 974,638. Presses for separating liquids from solids. EQUIPMENT DEVELOPMENT CO. Inc. May 18, 1962, No. 19310/62. Heading B1D. In a press for separating liquids from solids, e.g. sewage sludge, material A, Fig. 4, to be deliquefied is fed in a wet plastic condition down a shoot 20 on to a wire screen 11 carried by a rotating drum 10, the material being compressed by a roller 25, broken and turned by a scraper 96, compressed again by a roller 26, and collected in a deliquefied condition by a scraper 60 attached to a pivotally mounted shoot 61 situated above a belt conveyer; Fig. 2 (not shown). Liquid removed from the material is collected by a trough 63 having a drain outlet, Fig. 2, the screen being periodically washed by a water spray 65 located above the trough, as shown. The screen 11 comprises wires 75, Fig. 5, of trapezoidal cross-section, Fig. 6 (not shown), which are looped at intervals around cross wires 77. The wall of the drum 10 supporting the screen is a perforated shell 73 having a configuration comprising alternate lobes 71 and flutes 72, the rollers 25, 26 having complementary convex lobes 80 such that the zones in which the material A is compressed are of substantial and constant peripheral length. The roller 25 is mounted on cranked levers 27, Fig. 1, journalled on the ends of a shaft 30, their other ends being coupled to one another by a tray 33 carrying weights 34 to load the roller. The roller 26 is mounted in a similar manner on cranked levers 36 and is loaded by weights 44 in a tray 43 attached to a pair of levers 40 carried by stub shafts 41, a lug 45 on each lever 40 bearing downwardly on the free end of the associated lever 36. Downward displacement of the rollers is limited by screws 47 on the levers 27, 36, the ends of the screws bearing against the frame of the machine when the limit is reached. The rollers are driven at a peripheral speed substantially equal to that of the drum 10 by a variable speed motor 50 coupled to the rollers through inter-meshing spur gears 54, 55, the shaft 30, and roller chains 57, 58, the gear 55 also meshing with a gear wheel 56 attached to the drum. Scrapers 87, 91 carried by arms 88, 92, respectively, cleanse the surfaces of the rollers, the arms being pivotally attached to the associated levers 27, 36. The perforations in the shell 73 are of trapezoidal cross-section to permit any material adhering to the screen to pass into the interior of the drum, access to which is provided by large perforations in the end walls of the drum.

IPC: A01G15/00
Filed: 1923-07-30
Abstract: 201,574. Warren, L. F. July 29, 1922, [Convention date]. Meteorological conditions, local, apparatus for influencing.-Artificial rainfall or the coalescence and precipitation or dispersion of fogs and other atmospheric moisture is brought about by the artificial electrification of the atmosphere by scattering from a dirigible aircraft finely-divided particles of opposite electrical charge on the upper side of the cloud &c. An apparatus for carrying on an aeroplane &c. is shown in Fig. 1 in which an alternator 1 supplies a high-tension transformer 4, the secondary winding 5 of which is connected as shown through thermionic rectifiers 7 to a condenser 12, and thence through a reversing-switch 13 to a charging nozzle 14, shown in detail in Fig. 2. Fine dust from a hopper 16, Fig. 1, passes through the .annular space between an insulating tube 22, Fig. 2, and an inner conductor 20 connected to one side of the condenser 12, the other side of which is connected to an outer conductor 25. Instead of dust, positive or negative ions may be discharged to form nuclei for the condensation of moisture. This may be effected by trailing from the aeroplane a number of insulated wires connected to one terminal of the high-tension unidirectional device shown in Fig. 1, the other terminal being connected to the frame of the aeroplane, the charge on which is dispersed by needles on the upper wing of the machine or otherwise. The potential should be sufficient to cause a brush discharge from the trailing wires.

Patent GB-422564-A (GB)
Title: Improvements in and apparatus for the manufacture and production of monomethylamine and dimethylamine
Filed: 1933-07-10
Abstract: <PICT:0422564/IV/1> In a cyclic process for the manufacture of mono- and di-methylamine, one part of a mixture of 10 parts of methanol (or 8 of dimethyl ether) with about 6 parts of ammonia is mixed with 5--6 parts of an ammonia-trimethylamine mixture containing less trimethylamine than the azeotropic mixture of ammonia and trimethylamine, i.e. less than about 19 per cent by weight of trimethylamine; the parts referred to are parts by volume measured in the liquid state.  The mixture is led at a raised temperature, e.g. 300--450 DEG  C., and at a raised pressure over a dehydrating catalyst, e.g. alumina gel, and the reaction products are fractionally distilled under pressure, as described in Specification 421,486, to recover in turn (1) water, as a distillation residue, (2) an ammoniatrimethylamine mixture of a composition as stated above, this mixture being used again in the process in the manner described above, and (3) a mixture of mono- and di-methylamine, which is separated by fractional distillation.  The reaction may be effected under a pressure above 50 atm., as described in Specification 422,563.  As shown, ammonia and methanol (or dimethyl ether) are fed through a and b to a mixer M, to which ammonia-trimethylamine mixture is also fed through the line f.  The mixture is forced in turn through a heat-exchanger A, vaporizer V, and reaction vessel O, and the reaction products are passed through the heat-exchanger A, wherein they are condensed, and thence to a distillation column KI. The conditions of temperature and pressure in the column KI are such that water can be withdrawn at the base, while a mixture of the three methylamines and ammonia distils into the column KII.  In the latter column the conditions are such that ammonia and trimethylamine are distilled into the line f, leaving a mixture of mono- and di-methylamine which is passed to the column KIII for further fractionation.

Title: Improvements in or relating to valves
IPC: F16K1/08
Filed: 1931-07-09
Abstract: 390,841. Valve components. PATTISON, E. W., 51, Deansgate Arcade, Manchester.-(Schõffer & Budenberg Ges. ; Buckau, Magdeburg, Germany.) July 9, 1931, No. 19725. [Class 135.] Casings.-In a stop, back-pressure, reducing, or other valve, the resistance to the stream of pressure fluid is reduced to a minimum by constructing the fluid passage so that its axis approximates to the shape of an elongated letter " S " or an ogee laid along the longitudinal axis of the valve so as to lie on both sides of the same. The casing 11 of the stop valve shown in Fig. 1 has aligned inlet and outlet openings 12, 13. The fluid stream is first diverted downwardly below the longitudinal axis by the wall 16 and thereafter led obliquely through the valve seat opening 14 by a guiding wall 17. On the outlet side, the fluid stream is diverted back to the longitudinal axis by a wall 18. The cross section of the fluid passage may be gradually reduced up to the opening 14 and thereafter increased to its original diameter at the outlet 13. The bevelling of the valve seat 23 and of the valve face 22 as well as the provision of an eccentrically arranged space 20 assist in promoting stream-line flow conditions. The valve cover 24 which is secured to the casing 11 by means of screw-threaded studs and nuts has integrally formed bridge-arms 26 carrying a supporting-nut 27 for the screwed spindle 28, the arms 26 allowing ample room for the removal of a gland cover 29a, which may be secured to the cover by hinged bolts. In order to pack the stuffing-box 29 when the valve is in use, the valve member 15 is provided with a seating 30 which co-operates with a seating 31 on the valve cover. To secure the valve member to the spindle 28, a semi-annular filling piece 36, Fig. 6, engages an undercut recess 34 in the valve member and an annular groove 33 in the spindle, whilst a larger filling piece 37 engages the groove 33 and a slot cut in the valve member, the parts being held together by a sleeve 38, the upper end of which may act in place of the seating 30. In some forms, the fluid stream is led perpendicularly through the opening 14. The latter may be arranged above the longitudinal axis, as in Fig. 1, or below it. In one modification, the bridge arms are dispensed with and the cover is screwed directly into the valve casing. In this form, the valve face comprises a plastic core in a metal covering arranged in a recess in the valve member. In other forms, the valve face comprises a ring of nickel or stainless steel surface pressed, shrunk, or welded on to the valve member. The seat-member 23 may be of manganese bronze or nickel bronze. One form of back-pressure valve is shown, the valve stem being guided in the valve cover. Specifications 5344/08 and 164,266, [both in Class 135, Valves &c.], are referred to.
